For risk assessment of
ammonium sulphate the total topic of ammonia toxicity was regarded.
Species mean chronic values (SMCV), as given by U.S. EPA (1999) were
considered as relevant endpoints. The
lowest species mean chronic value was calculated for Lepomis macrochirus
EC20 = 1.35 mg N/L and EC10 = 1.12 mg N/L = 5.29 mg/L Ammonium sulphate
(Smith et al. 1984, adjusted to pH 8 and 25°C).
